Some Repeater Problems

I have been messing around with enyo, and am trying to populate a repeater with data from an API call. I keep getting an error in the setupWorlds function though: cannot call method 'setContent' of undefined. Please note i actually used Ares to make this. Not sure what I am doing wrong. see code below:

so I added the var item= inEvent.itemBut i still get an error on this line: this.$.worldName.setContent(worldInfo.name+" --- ");Error is: Uncaught TypeError: cannot call method 'setContent' of undefined.

It's because you're still accessing this.$.worldName instead of item.$.worldName, at least according to that error. inEvent.item is the delegate/wrapper control for the item being rendered at that time and named components of that row (worldName, for instance) are owned by that delegate, not this.
